Q10. What is the NUFF? What does it cover and how is it computed?
A10. The NUFF is a one-time fee paid by the property owner at the time of connection of a new service lateral to the collection line. It grants the property owner the right to discharge sewer to the collection system. The purpose of the NUFF is to cover the sewer district’s cost to convey and treat the wastewater. Building new pipes, pump stations and treatment plants is expensive.  The NUFF ensures that the cost of infrastructure is distributed to customers fairly and helps make sure that “growth pays for growth.”

At this time, the New User Facility Fee (NUFF), also known as a permit or connection fee, is $5,811.00 for a single residence. The NUFF is transferrable with change of ownership but remains with the parcel for which it was paid. The District reviews the cost every few years and it is subject to change to account for the latest infrastructure improvements. The NUFF amount is calculated according to a formula established by the Idaho Supreme Court: (Net Present Day Value of System) ÷ (Number of Users System can Support).

Q11. How much is the NUFF and how is it computed?

A11. The NUFF fee for Residential and Commercial users is $5811.00. It is computed by the Supreme Court dictated formula; Net present day value ÷ number of users current system can support.

Q12. Does the NUFF cover construction costs?
A13. No, the customer is responsible for all construction costs to install a new sewer lateral and connect it to the collection line. Some properties also require a septic tank to be installed by the customer depending on the location.

Q13. Is there a separate NUFF for the cities of Mullan, Wallace, Osburn and Kellogg?
